I'm a bit confused about what you're asking. You discuss antennas but you show pictures of a GPS receiver. They're not the same thing. I use a puck antenna. They cost about $6 on ebay, and take their power from the coax. Normally your GPS receiver supplies power to the coax, so you don't have to do anything special, other than don't short it out.

I had asked whether I should apply 5 volts to the. tom posted on his fine info page a pinout, which I'm going to use. Pin 1 is 3-5.5VDC Antenna power input. Pin 2 is Prime Power input pin 4 is Backup Power input. Pin 8 is GND I am going to apply 3.3 to 1,2, and 4. Just wanted to get an opinion before trying it. I'm curious if somehow the suggested Primary and Backup power was all that was needed, or how you guys were getting your GPS signals in. Are your antennas not powered? thanks Jim http://leapsecond.com/pages/itrax/ _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there. _______________________________________________ time-nuts mailing list -- time-nuts@febo.com To unsubscribe, go to https://www.febo.com/cgi-bin/mailman/listinfo/time-nuts and follow the instructions there.
